Frequently Asked Questions

Is it safe to type my real password into this checker?

Yes. The Password Strength Checker runs only in your browser. Your password is never sent to any server or stored anywhere.

How is password strength calculated?

The tool looks at length, character variety (upper/lowercase, numbers, symbols) and patterns like repeated characters to estimate how hard your password is to guess.

Should I reuse a strong password on multiple sites?

Even if the password is strong, you should avoid reusing it. Use a unique strong password for each important account, ideally stored in a password manager.
